why is physics useful?

Answer 1

☺ it’s useful as well as other branches of science; physics provides technological progress but does not make humanity happier, and causes new problems;

Answer 2

Physics is useful because it encompasses all of science. In your everyday life you use physics all the time. When driving in your car and you determine how fast you are going or when you should apply the brakes that's physics. Physics is also seen in both Chemistry and Biology. Physics is perhaps the most general all around science.

Answer 3

Physics is the science of matter and how matter interacts. Physics is used to describe the physical universe around us, and to predict how it will behave. Physics is the science concerned with the discovery and characterization of the universal laws which govern matter, movement and forces, and space and time, and other features of the natural world.

Physics is the study of matter and energy and how they work with each other. Physics studies how things move, and the forces that make them move. For example, velocity and acceleration are used by physics to show how things move. Also, physicists study the forces of gravity, electricity, magnetism and the forces that hold matter together.

Physics studies very large things, and very small things. For example, physics studies stars, planets and galaxies and other big pieces of matter. Physics also studies small pieces of matter, such as atoms and electrons.

Physics also studies sound, light and other waves. Physics studies energy, heat and radioactivity, and even space and time. Physics not only helps people understand how objects move, but how they bend, how they make noise, how hot or cold they will be, and what they are made of at the smallest level.

Classical physics traditionally included the fields of mechanics, optics, electricity, magnetism, acoustics and thermodynamics. Modern physics is a term normally used to cover fields which rely on quantum theory, including quantum mechanics, atomic physics, nuclear physics, particle physics and condensed matter physics, as well as the more modern fields of general and special relativity. Although this distinction can be commonly found in older writings, it is of limited current significance as quantum effects are now understood to be of importance even in fields previously considered purely classical.

Over the years, one thing scientists have discovered is that nature is generally more complex than we give it credit for. The following laws of physics are considered fundamental, but many of them refer to idealized, closed systems, which are hard to obtain in the real world. Also, some are altered slightly in different circumstances. Newton's laws of motion, for example, are modified by the findings of the theory of relativity, but they are still basically valid.

Answer 4

Understanding physics is like understanding science just because you feel like it.

There aren't any uses for physics except for disproving theories, and proving new ones. Although, you can't really do anything with the theories. So people learn physics just because they can, or they actually think its fun.

Answer 5

It underlies all the other physical sciences and engineering.

Studying physics (like studying math) makes you smarter and more able to solve all sorts of problems that might come your way.

Answer 6

Physics is the basis for the rest of science and all of engineering.
